20, 1966. This application Oct. 31, 1968. Published Apr. 22, 1969 Class 260--29.6 N0 Drawing. 16 Pages Specification A process for finishing textile fabrics which comprises contacting a textile fabric with an aqueous dispersion of an cmulsifiable low molecular weight modified polyethylene composition, having a saponification number of at least 6, a melt viscosity of about .1 to .5. The modified polyethylene composition is obtained by reacting a low molecular weight crystallizable polyethylene having an inherent viscosity of about .1 to about .5 with unsaturated polycarboxylic acids, unsaturated polycarboxylic acid anhydrides or unsaturated polycarboxylic acid esters at a temperature of 200 to 400 C. The aqueous dispersion contains about 20 to about 45% by weight solids. These dispersions arc diluted to a solution containing 2 weight percent modified polyethylene and about 25 Weight percent of :a permanent press thcrrnosetting resin is added to this solution. This solution is then padded onto a textile fabric to obtain a 70 percent Wot pick up and then air dried. The textile fabric can then be hot pressed to impart a permanent press to garments prepared therefrom.
